Approaches to 3D Image Reconstruction from Motion Scattered Diffusion Weighted MRI of the Fetal Brain

Talk Title: Approaches to 3D Image Reconstruction from Motion Scattered Diffusion Weighted MRI of the Fetal Brain

Series: Medical Imaging Seminar Series

Abstract: Magnetic resonance based diffusion weighted imaging provides a unique window into tissue microstructure and brain connectivity. Over the last 7 years there has been significant interest in adapting the technique using post-processing to enable imaging of the unsedated fetal brain in-utero. This talk will review work on reconstruction of diffusion image measurements from single shot multi slice diffusion MRI data, where significant motion has occurred between the acquisition of slices. To form a complete 3D image of diffusion properties during head motion each diffusion weighted slice must be accurately relocated and orientated within a common anatomical coordinate system, and the spatially scattered slices then used to estimate a model of diffusion properties on a regular voxel lattice. This talk will look at these two problems and review the current alternatives to solving them numerically for clinically acquired data. Results on human and primate fetal brain data will be included to illustrate the capabilities and limitations for practical studies of fetal brain growth.
